摘要： An optical scanning device includes a light-source unit that emits a plurality of light beams, a deflector that deflects the light beams, and an image-forming optical system that receives the light beam deflected by the deflector and forms a spot image on photoconductors. The image-forming optical system includes a first scanning lens that allows only a corresponding light beam to pass and is arranged to form, upon receiving a virtual light beam, the spot image on the photoconductor with a not-curved line. The virtual line lies between a pair of light beams that travels in one of areas separated by a reference plane that is parallel to a sub-scanning direction and on which a normal line to a deflection plane of the deflector falls.

摘要： In a light beam scanning device, a plurality of light sources, which irradiates a plurality of light beams in a first direction and is retained by a holder, are disposed at distance from one another in a second direction orthogonal to the first direction. The plurality of light beams are incident, via a coupling optical system, to deflecting and reflecting surfaces of a deflector from a direction that is tilted with respect to a plane orthogonal to the rotational shaft of the deflector. The holder is supported by a housing of the light beam scanning device at a plurality of different positions in a third direction extending from the light source to the coupling optical system.
